Does anyone have the schematics or even a photo and details like parts lists of the insides of the mc-10 16k memory pack? Anyone have one for sale? Thanks!

They're a mess inside - two circuit boards stuffed with parts. I guess it was cost effective at the time - 8 DRAMs and decoder parts. I would be inclined to use a single 64 K SRAM nowadays and mask out the areas used by the MC-10 itself if necessary. If you want one, eBay is the place, or try the MC-10 list http://groups.yahoo.com/group/trs80mc10club/ N

They're a mess inside - two circuit boards stuffed with parts. I guess it was cost effective at the time - 8 DRAMs and decoder parts. I would be inclined to use a single 64 K SRAM nowadays and mask out the areas used by the MC-10 itself if necessary. I was thinking that it could just be a single SRAM inside, but then thinking about how much a single large capacity SRAM would cost in those days... If you want one, eBay is the place, or try the MC-10 list http://groups.yahoo.com/group/trs80mc10club/ Ok thanks for that I have joined the club.
